The A-100 is really cool, does it still have the straight axle in the front?
I had a 69 van and it really drove like ****.
More recently I had a 71 D-100 as a daily driver, yes with everything rebuilt in the front, it really still drove like ****.
Drive the truck, not necessary getting on to see how fast it will go, but nice and easy to see how it reacts to normal road conditions.
